Building Facade Safety Inspection
Continuous occurrences of curtain wall hazard accidents necessitate regular safety inspections and testing to enhance prevention, reduce harm, and ensure urban safety.
A building facade refers to the outer protective system of a building, consisting of panels and supporting structures. It has a certain displacement capability relative to the main structure, and in addition to transmitting its own loads to the main structure, it does not bear the effects exerted on the main structure.
The inspection and evaluation of building curtain walls should be conducted in accordance with the following procedures:
1. Commission
2. Inquiry
3. Develop inspection and testing plans
4. Inspection and Testing
5. Calculation and Analysis
6. Inspection and Assessment Report.
The principal shall provide technical documents for engineering design, construction, and use, and determine the content of the inspection and evaluation with the inspection party. When entrusting inspection and evaluation, drafting, and negotiating the inspection and testing plan, the responsibilities and risks of the principal and the inspection party should be clearly defined.
The survey should include the following tasks:
1. Project Overview: Includes the start and completion time, engineering structure, construction unit, design unit, construction unit, supervision unit, etc.
2. Technical Documents: Including completion drawings for curtain wall projects, structural calculation books, design change records, etc.
3. Quality Assurance Documents for Construction Projects: Including completion reports, concealed work acceptance records, quality inspection records of construction, material quality assurance certificates, material retest reports, etc.
4. Record of facade usage in construction: including daily maintenance and repairs, condition logs, renovation completion technical documents, etc.
5. On-site Adjustments: Verify physical items against documentation, investigate the actual internal and external environment of the building and its usage conditions, inspect and report existing issues, and collect opinions from relevant personnel.
Based on the various documents and investigation information provided by the client, determine the key items for inspection and testing. Develop a comprehensive inspection and testing evaluation plan, which should include the content, methods, and schedule of the inspections and tests.
Building Facade Inspection and Testing Services:
1. Basic inspection: facade system, structure, key joints, and opening panel installation quality.
2. Current Condition Inspection: panel and connection component damage, rust, deformation, and extent of hardware failure.
3. Material inspections: panels, metal profiles, silicone structural sealant, stone adhesives, sealing materials, fire-resistant insulation materials, hardware, pre-bolted parts, and retrofitted embedment parts, etc.
4. Structural and Construction Inspection: Load-bearing members and structures, panel assembly components, etc.
5. Structural Load-Bearing Verification: Verification of loads acting on container walls, their effects, and node verification.
